Fig. 1 is a schematic structural diagram of a flexible display module in the related art. As shown in fig. 1, the flexible display module includes a flexible display panel 11 and a support 12. The flexible display panel 11 has opposite front and back surfaces, wherein the front surface is a display surface for displaying. The flexible display panel 11 is located on one side of the support 12, and the back side of the flexible display panel 11 is opposite to the support 12 and is connected to the flexible display panel 11, for example, by being adhered by a pressure sensitive adhesive layer 13. In assembling an electronic device, the flexible display module is typically placed on an assembly table and then attached to the folding bezel, for example, by pressure sensitive adhesive bonding. Because flexible display module assembly is flexible, when placing on the assembly bench and folding center be connected, the precision of pasting is difficult to control, leads to producing great deviation easily when pasting.

Fig. 2 is a schematic structural diagram of a support member of a flexible display module according to an embodiment of the present disclosure. As shown in fig. 2, the support member includes a main body portion 20 and a plurality of external protrusions 30. The plurality of outward protrusions 30 are distributed at least at two opposite lateral sides of the main body portion 20, and are convex outward relative to the lateral sides of the main body portion 20. The outward protrusion 30 has a positioning hole 30a.

Fig. 3 is a schematic structural diagram of an assembly table according to an embodiment of the present disclosure. As shown in fig. 3, the assembly table includes a support portion 40 and a plurality of positioning posts 50, the support portion 40 has a support surface 40a, the support surface 40a is used for bearing the support member, the plurality of positioning posts 50 stand on the support surface 40a and are connected to the support surface 40a, and the plurality of positioning posts 50 are used for being matched with the positioning holes 30a of at least part of the outer convex portion 30 of the support member.

In the process of manufacturing the electronic device, the flexible display module can be placed on the supporting surface 40a, at least part of the outer protruding portion 30 of the supporting member is sleeved on the positioning column 50, and the flexible display module is positioned by matching the positioning column 50 with the positioning hole 30a of the outer protruding portion 30. So when making the equipment flexible display module assembly and folding center, only need to fix a position folding center and holding surface 40a, just can ensure that the deviation of the relative position between flexible display module assembly and the folding center is less.

As shown in fig. 3, the positioning column 50 includes a first section 51 and a second section 52, the first section 51 is a straight column, and the second section 52 is a table. One end of the first segment 51 is connected to the support surface 40a, and the other end of the first segment 51 is connected to the larger end of the second segment 52.

Illustratively, the first section 51 is cylindrical and the second section 52 is frustoconical. Alternatively, the first section 51 is prismatic and the second section 52 is truncated.

The second section 52 is a table body, and can play a role in guiding when the positioning hole 30a is sleeved on the positioning column 50, so that the flexible display module can be conveniently positioned.

The shape of the first segment 51 is related to the shape of the corresponding positioning hole 30a. For example, the positioning hole 30a is circular or oval and the first section 51 is cylindrical. For another example, the positioning hole 30a is rectangular, and the first section 51 is quadrangular.

Alternatively, the length of the first section 51 is not less than the depth of the positioning hole 30a, so that when the positioning hole 30a is sleeved outside the positioning column 50, the entire hole wall of the positioning hole 30a can be matched with the outer wall of the first section 51.

The lengths of the positioning posts 50 may be the same or different for different positioning posts 50. For example, the positioning posts 50 for engaging with the outer convex portions 30 located on the opposite sides of the main body 20 have the same length, and the positioning posts 50 for engaging with the outer convex portions 30 located on the adjacent sides of the main body 20 have different lengths.

In some examples, the positioning posts 50 are arranged in a one-to-one correspondence with the positioning holes 30a, when the flexible display module is positioned, the positioning posts 50 are inserted into the corresponding positioning holes 30a, and one positioning post 50 is inserted into each positioning hole 30a. In other examples, the number of the positioning posts 50 may also be less than that of the positioning holes 30a, when the flexible display module is positioned, the positioning posts 50 are inserted into the positioning holes 30a, a part of the positioning holes 30a is not sleeved outside the positioning posts 50, and the function of the part of the positioning holes 30a that is not sleeved outside the positioning posts 50 will be described later.

In the supporting member of the flexible display module, by providing the convex outer protrusion 30 at the side of the main body portion 20, the outer protrusion 30 has a positioning hole 30a, when assembling the flexible display module and folding the middle frame, the flexible display module can be placed on the assembling table, and the positioning hole 30a of the outer protrusion 30 is matched with the positioning column on the assembling table for positioning. Because the outer convex part 30 distributes in two relative side departments of main part 20 of support piece at least, consequently can make the flexible display module keep the horizontality when the location, be favorable to improving the laminating precision of flexible display module and folding center, reduce the laminating deviation.

Optionally, the main body portion 20 has a first face and a second face opposite to each other, the first face is used for connecting the flexible display panel, and a face of the outer convex portion 30 close to the second face is coplanar with the second face of the main body portion 20. When placing the flexible display module on supporting surface 40a like this, the second face of main part 20 and the one side of evagination 30 all can paste with supporting surface 40a, what make the flexible display module place is more steady.

In other examples, a surface of the protruding portion 30 close to the second surface may not be coplanar with the second surface of the main body portion 20, for example, the protruding portion 30 is entirely located on a side of the plane of the second surface of the main body portion 20 close to the first surface.

Fig. 4 is a top view of a support provided by embodiments of the present disclosure. As shown in fig. 4, in the supporting member, the main body portion 20 has two opposite first sides 20a and two opposite second sides 20b, and two ends of each of the two second sides 20b are respectively connected to the two first sides 20a.

The first side edge 20a intersects the second side edge 20b, e.g., the first side edge 20a and the second side edge 20b are perpendicular to each other.

The main body portion 20 has a bending region 201, and the bending region 201 extends from one first side edge 20a to the other first side edge; at least one outward protrusion 30 is connected to each of the two second sides 20b.

As an example, in the strut shown in fig. 4, two male portions 30 are connected to each second side edge 20b. In other examples, one convex portion 30 may be connected to each second side 20b, or a greater number of convex portions may be connected to each second side 20b, and the number of convex portions 30 connected to each second side 20b may be set based on the length of the second side 20b. When the plurality of protruding portions 30 are connected to the second side 20b, the plurality of protruding portions 30 may be equally spaced along the second side 20b.

The bending region 201 has a hollow structure. The hollow structure may include a plurality of through holes. For example, as shown in fig. 4, a plurality of strip-shaped through holes 201a are distributed in the bending region 201, and the length directions of the plurality of strip-shaped through holes 201a are all parallel to the second side edge 20b. By arranging a plurality of strip-shaped through holes 201a in the bending region 201, the rigidity of the support member in the bending region 201 is reduced, so that the support member can be bent in the bending region 201. When the flexible display module is folded, the two first side edges 20a are bent, and the two second side edges 20b are relatively close to each other.

The hollow structure shown in fig. 4 is only an example, and in other possible implementation manners, the hollow structure may also include through holes with other shapes, and the shapes of different through holes may be the same or different, and the sizes of different through holes may be the same or different.

The arrangement mode of bending zone 201 makes flexible display module produce deformation along the axle of buckling of bending zone 201 relatively easily, through arranging outer convex part 30 in two second sides 20b departments of main part 20 for when assembling electronic equipment, can utilize the outer convex part 30 of second side 20b department to cooperate with the reference column on the assembly bench, avoid flexible display module to produce deformation along the axle of buckling of bending zone 201, make flexible display module keep leveling.

The supporting member may be made of a metal material, such as stainless steel, and the main body portion 20, the outer protrusion portion 30, the positioning hole 30a, the strip-shaped through hole 201a, and the like of the supporting member may be formed by stamping.

As shown in fig. 4, in the embodiment of the present disclosure, an outward protrusion 30 is connected to one first side 20a of the main body portion 20.

By providing the convex portion 30 also on the first side 20a of the main body portion 20, the positioning accuracy of the flexible display module can be further improved at the time of assembly.

Illustratively, a plurality of outward protrusions 30 are connected to one first side 20a of the main body 20. Such as the support member shown in fig. 4, two male portions 30 are connected to one first side edge 20a of the main body portion 20. The two outer protrusions 30 are symmetrically arranged about the inflection zone 201. The convex portions 30 of the two second sides 20b of the main body portion 20 may also be arranged symmetrically about the bending region 201.

In an electronic apparatus, the flexible display module is generally connected to other devices, such as a printed circuit board, a battery, etc., through a flexible circuit board, which extends from one first side edge 20a of the main body portion 20 opposite to the flexible display module. In the supporting member shown in fig. 4, the convex portion 30 is disposed only on one first side edge 20a, and the convex portion 30 is not disposed on the other first side edge 20a, so that when the flexible display module is manufactured, the flexible circuit board can protrude from the first side edge 20a where the convex portion 30 is not disposed, thereby avoiding the influence on the arrangement of the flexible circuit board.

As an example, fig. 5 is a schematic structural diagram of a support provided in an embodiment of the present disclosure. As shown in fig. 5, in the supporting member, the convex portions 30 are disposed on both first sides 20a of the main body portion 20. Although the flexible circuit board protrudes from one first side edge 20a of the main body portion 20, it does not generally occupy the entire space at the first side edge 20a. The convex portions 30 are provided at positions capable of avoiding the flexible circuit board at the first side edges 20a, so that the flexible circuit board can be further positioned from the two first side edges 20a without affecting the arrangement of the flexible circuit board.

The outer protrusion 30 may have a rectangular shape, a square shape, a semicircular shape, or the like. For example, the convex portion 30 shown in fig. 5 is a square, and the length of each of the two sides is 5mm to 8mm.

Alternatively, the positioning hole 30a may be one of a circular hole, an elliptical hole, and a strip-shaped hole. Wherein, the bar hole is the hole that has a set of parallel opposite side, and length is greater than the width, including but not limited to, rectangle hole, waist round hole, fillet rectangle hole, hexagon hole. As an example, a rectangular hole is exemplified in the embodiment of the present disclosure.

Different shapes of the holes can achieve different positioning effects. For example, when the round hole is matched with the positioning column, in the radial direction of the round hole, the range of gaps between the hole wall of the round hole and the outer wall of the positioning column is the same, that is, the positioning accuracy in all directions is the same. When the positioning hole 30a is an elliptical hole, the longitudinal direction of the positioning hole 30a is the major axis direction of the elliptical hole, and the width direction is the minor axis direction of the elliptical hole. The oval holes have different lengths and widths, which causes the gaps between the positioning posts and the hole walls of the oval holes to be different in the length direction and the width direction of the oval holes, that is, the positioning accuracy is different in the length direction and the width direction of the oval holes.

Alternatively, at least two of the plurality of the convex portions 30 have different positioning holes.

The positioning holes 30a in at least two different shapes are arranged for positioning, so that the positioning is convenient, and the positioning precision is high.

Illustratively, the plurality of outward protruding portions 30 includes at least a first outward protruding portion 301 and a second outward protruding portion 302, wherein the positioning hole of the first outward protruding portion 301 is a circular hole, the positioning hole of the second outward protruding portion 302 is an elliptical hole having a minor axis length greater than the diameter of the circular hole or a strip-shaped hole having a width greater than the diameter of the circular hole, the first outward protruding portion 301 is connected to the first side edge 20a, and the second outward protruding portion 302 is connected to the second side edge 20b.

Fig. 6 is an enlarged view of a portion a in fig. 4, and as shown in fig. 6, in the supporting member, the positioning hole 30a of the first outward protruding portion 301 is a circular hole. Fig. 7 is an enlarged view of B in fig. 4, and fig. 8 is an enlarged view of C in fig. 4, and as shown in fig. 7 and 8, the positioning hole 30a of the second outward protrusion 302 is an elliptical hole.

When the flexible display module is positioned, the round holes are used for fine positioning, the positioning columns 50 are difficult to align, the oval holes are used for coarse positioning, and the positioning columns 50 are easy to align. Fig. 9 is a schematic diagram of the engagement between the external protrusion and the positioning post according to the embodiment of the disclosure. As shown in fig. 9, the positioning holes 30a of the second outer convex portion 302 are inserted into the corresponding positioning posts 50, and the flexible display module has a high positioning accuracy in the width direction of the elliptical hole, and can only move to a small extent or cannot move, while the positioning accuracy in the length direction of the elliptical hole is relatively low, and can move to a small extent. The oval hole roughly positions the flexible display module, so that the round hole can be aligned to the positioning column 50 more easily and sleeved outside the corresponding positioning column 50. After the round hole is sleeved on the corresponding positioning column 50, the flexible display module is limited, so that the flexible display module cannot move or can only move in a small amplitude in the length direction of the elliptical hole.

In the supporting member shown in fig. 9, the processing precision of the circular hole is greater than the processing precision of the elliptical hole and the rectangular hole, when one first outer protruding portion 301 is disposed on the first side edge 20a, the circular hole of the first outer protruding portion 301 is sleeved outside the positioning post 50, the flexible display module may still be able to move in a very small range in the length direction of the elliptical hole, by disposing two first outer protruding portions 301 on the first side edge 20a, since the distance between the positioning posts 50 matched with the two first outer protruding portions 301 of the first side edge 20a is fixed, the circular holes of the two first outer protruding portions 301 are respectively sleeved on the two positioning posts 50, the moving range of the flexible display module can be further limited, and the positioning precision of the flexible display module is further improved. And support piece's preparation has certain size and geometric tolerances, and the round hole of two first outer convex parts 301 carries out the location of higher accuracy to first side 20a, makes support piece's tolerance can be on average to flexible display module's both sides, also namely second side 20b department to make the electronic equipment assemble the back of accomplishing, the display screen can be placed in the middle better.

Optionally, the length direction of the positioning hole 30a of the second outward protruding portion 302 is perpendicular or parallel to the second side edge 20b. In fig. 9, the positioning hole 30a of the second outward protrusion 302 is an elliptical hole, the length direction of the positioning hole 30a is the long axis direction of the elliptical hole, and the long axis of the elliptical hole is perpendicular to the second side edge 20b.

For example, in the example shown in fig. 9, the length direction of the positioning hole 30a of the second outward protruding portion 302 is perpendicular to the second side edge 20b. After the positioning hole 30a of the second outward protruding portion 302 is sleeved on the positioning post 50, the positioning accuracy of the flexible display module is higher in the width direction of the positioning hole 30a, that is, in the direction parallel to the second side edge 20b, and only a small amount of movement or no movement can be performed, and the positioning accuracy of the flexible display module is slightly lower in the direction perpendicular to the second side edge 20b, and a certain amount of movement can be performed, after the positioning hole 30a of the first outward protruding portion 301 is completely sleeved on the positioning post 50, the positioning accuracy of the flexible display module is also higher in the direction perpendicular to the second side edge 20b, and only a small amount of movement or no movement can be performed.

In other examples, such as shown in fig. 10, the length direction of the positioning hole 30a of the second outward protrusion 302 is parallel to the second side edge 20b. After the positioning hole 30a of the second external convex portion 302 is sleeved on the positioning column 50, in the width direction of the positioning hole 30a, that is, in the direction perpendicular to the second side edge 20b, the positioning accuracy of the flexible display module is high, and only a small amount of movement or no movement can be performed, in the direction parallel to the second side edge 20b, the positioning accuracy of the flexible display module is slightly low, and a certain amount of movement can be performed, after the positioning hole 30a of the first external convex portion 301 is completely sleeved on the positioning column 50, in the direction parallel to the second side edge 20b, the positioning accuracy of the flexible display module also becomes high, and only a small amount of movement or no movement can be performed.

Fig. 11 is a schematic structural diagram of a support provided in an embodiment of the present disclosure. As shown in fig. 11, in the supporting member, two second outer convex portions 302 are connected to each second side 20b of the main body portion 20, and at least one second side 20b, the length directions of the positioning holes 30a of the two second outer convex portions 302 connected to the same second side 20b are perpendicular to each other.

To fit the oval positioning holes 30a on the corresponding positioning posts 50, the oval positioning holes 30a need to be aligned with the positioning posts, that is, the orthographic projections of the end surfaces of the positioning posts far away from the supporting surface of the assembly table on the supporting surface are located in the orthographic projections of the positioning holes 30a on the supporting surface of the assembly table. In the alignment, the position of the flexible display module with respect to the positioning posts needs to be adjusted in the longitudinal direction and the width direction of the positioning holes 30a, and since the length of the positioning holes 30a is larger than the width, the adjustment in the longitudinal direction of the positioning holes 30a is easier.

To the great flexible display module assembly of area, there may be certain deformation in the transportation to the degree of difficulty of alignment is increased. In this example, the length directions of the positioning holes 30a of the two second outer convex portions 302 connected to one second side 20b are set to be perpendicular to each other, so that when aligning, no matter the flexible display module is moved in the direction perpendicular to the second side 20b or in the direction parallel to the second side 20b, one of the oval positioning holes 30a can be aligned with the positioning column more quickly, and as long as one oval positioning hole 30a is aligned with and sleeved on the positioning column, the other oval positioning holes 30a can be aligned with the corresponding positioning column quickly. After the positioning columns are aligned to the two oval positioning holes 30a which are perpendicular to each other in the length direction, the flexible display module has high positioning accuracy in two perpendicular directions, and the positioning columns are easily aligned to the round positioning holes 30a.

Optionally, the diameter of the circular hole is less than the minor axis length of the elliptical hole. The diameter of the round hole is smaller than the length of the short axis of the elliptical hole, when the round hole and the elliptical hole are machined, the round hole has higher machining precision, and during positioning, the round hole can have higher positioning precision.

Illustratively, the elliptical holes have a minor axis length that is 1.1 to 1.5 times the diameter of the circular hole.

Optionally, the ratio of the length to the width of the positioning hole 30a of the second outer convex portion 302 is (1, 1.3) for the elliptical hole, that is, the ratio of the length of the long axis to the length of the short axis is (1, 1.3). The length of the long axis of the elliptical hole is slightly greater than the length of the short axis, if the length difference is too large, the positioning accuracy of the elliptical hole in the direction of the long axis is too low, which is not favorable for the alignment of the circular hole and the positioning column.

Fig. 12 is a schematic structural diagram of a support provided in an embodiment of the present disclosure. As shown in fig. 12, the supporting member is different from the supporting member shown in fig. 9 in that, in fig. 12, the positioning hole 30a of the second externally protruding portion 302 is a rectangular hole. The length of the rectangular hole is larger than the width of the rectangular hole, and the rectangular hole has basically the same effect as the elliptical hole when positioning is carried out.

When fixing a position flexible display module assembly, what the round hole went on is meticulous location, and difficult alignment reference column 50, the rectangle hole is the same with the elliptical aperture, and what go on is also thick location, aligns reference column 50 more easily. The positioning holes 30a of the second outer protruding portions 302 are sleeved on the corresponding positioning posts 50, the flexible display module has higher positioning accuracy in the width direction of the rectangular hole, and can only move to a smaller extent or cannot move, and has relatively lower positioning accuracy in the length direction of the rectangular hole, and can move to a larger extent. The rectangular holes are used for roughly positioning the flexible display module, so that the round holes are aligned to the positioning columns 50 more easily and are sleeved outside the corresponding positioning columns 50. After the round holes are sleeved on the corresponding positioning columns 50, the flexible display module is limited, so that the flexible display module cannot move or can only move in a very small amplitude in the length direction of the rectangular holes.

The length direction of the positioning hole 30a of the second outward protrusion 302 is perpendicular or parallel to the second side edge 20b. In fig. 12, the positioning hole 30a of the second outward protruding portion 302 is a rectangular hole, the length direction of the positioning hole 30a is the length direction of the rectangular hole, that is, the long side direction of the rectangular hole, and the long side of the rectangular hole is perpendicular to the second side edge 20b.

Alternatively, the ratio of the length to the width of the rectangular hole is (1, 1.3), for the rectangular hole, that is, the ratio of the length of the long side to the length of the short side is (1, 1.3), the length of the long side of the rectangular hole is slightly greater than the length of the short side, if the length difference is too large, the positioning accuracy of the rectangular hole in the direction of the long side is too low, which is not favorable for the alignment of the circular hole and the positioning column 50.

Optionally, the width of the strip-shaped hole is 1.1 to 1.5 times the radius of the circular hole. For a rectangular hole, the length of the short side of the rectangular hole is 1.1 to 1.5 times the radius of the circular hole. The width that sets up the diameter of round hole than the bar hole is littleer, and when processing round hole and rectangular hole, the round hole has higher machining precision, and during the location, the round hole can have higher positioning precision.

In some examples, a plurality of protruding portions 30 are connected to the at least one second side edge 20b, and the positioning hole 30a of at least one of the plurality of protruding portions 30 is a rectangular hole, and a long side of the rectangular hole is perpendicular or parallel to the second side edge 20b. When positioning, the positioning hole 30a of the external protrusion 30 is not inserted outside the positioning post 50. The rectangular positioning hole 30a of the convex portion 30 can be used for monitoring. After the flexible display module is delivered to the assembly table, whether the orientation of the flexible display module is accurate or not can be determined according to the included angle between the long edge or the short edge of the positioning hole 30a and the mark line used as a reference. The mark line used as a reference is a mark line used for indicating the upper direction, the lower direction, the left direction, the right direction or other directions of the display area of the flexible display module when the flexible display module is flatly placed on the supporting surface. The marking line may be located on the support surface. The direction of the flexible display module can be more accurately determined through the rectangular positioning hole 30a and the marking line, so that when the flexible display module displays a picture, the upright direction of the picture can be parallel to or perpendicular to the frame of the electronic equipment.

In the example shown in fig. 15, both the first bar-shaped groove 303 and a plurality of through holes 304 are provided, and the through holes 304 are located in the first bar-shaped groove 303. This can further reduce the structural strength at the junction of the convex portion 30 and the main body portion 20, facilitating removal of the convex portion 30.

As shown in fig. 15, a second elongated groove 305 may be further provided at the bottom of the first elongated groove 303, and the second elongated groove 305 extends along the edge of the main body portion 20. By further providing the second strip-shaped groove 305 at the bottom of the first strip-shaped groove 303, the structural strength of the joint of the outer convex part 30 and the main body part 20 can be further reduced, and when the outer convex part 30 is removed in a bending mode, the support part can be ensured to be broken from the second strip-shaped groove 305, and the broken part is smoother.

At least one first outward protrusion 301 and at least one second outward protrusion 302 are connected to both second sides 20b. The first outward protrusion 301 connected to the second side 20b is adjacent to the first side 20a to which the second outward protrusion 302 is connected; the second outward protrusion 302 connected to the second side 20b is adjacent to the first side 20a to which the first outward protrusion 301 is connected.
